AI Coach · Range interpretation
How to interpret this BB vs BTN range
This 40bb BB vs BTN open preset pairs a pure 3-bet top end with a wide, mostly call-heavy suited defense.
The grid shows AA–99 plus AKs, AQs, AKo, and AQo as pure 3-bets, while 88 and several broadway holdings mix. A useful study pattern is that AJs–A2s are pure calls, whereas suited connectors use notably different 3-bet/call mixes.
Suited aces split at the top
AKs and AQs are pure 3-bets, while every suited ace from AJs through A2s is a pure call.
Connector mixes are uneven
98s and 54s are 3-bet weighted, while T9s, 87s, and 65s are call weighted; 76s is a pure call.
Memorize three rows separately—pairs, suited aces, and suited connectors—then quiz the action mix for 88, 98s, 54s, and 76s.
